Only one app running in MAC?

Question

Hi,

Does this code work on MAC, only one app running ?

Thanks,

public partial class App : Application

{

 private static Mutex mutex = new Mutex(true, Assembly.GetEntryAssembly().GetName().Name);

 public App()

 {

     if (!mutex.WaitOne(TimeSpan.Zero, true))

     {

         Current.Quit();

         Environment.Exit(0);

     }

not on any O/S. The .net Mutex instance is tried to the process, its basically a static variable.

if a name string is passed, a system mutex is used and works.

On windows you would use the NT named mutex. On MacOS you would use the named pthread mutexes. if you pass a string, .net uses O/S mutex.

On MacOs the Desktop already defaults to one instance, but you can start a second via terminal. But rather than a named mutex it is better to use NSWorkspace which has a list of running applications.
